Question

这是我的代码：

[HttpPost]
public ActionResult Edit(int id)
{
   var viewModel = service.GetUserViewModel(id);
   return View(viewModel); // reponse the ValidateLogin view
}

[HttpPost]
public ActionResult EditDetails(UserDetails userDetails)
{
    return Edit(userDetails.Id);
}

不幸的是，它没有返回视图，但是却给了我错误。怎么了？

您无法使用[HttpPost]从标有return Edit(userDetails.Id)的其他动作中返回视图，而是必须将一个动作设置为[HttpGet]（即Edit动作方法）并使用RedirectToAction() overload which has route value parameter调用该操作，如下例所示：

[HttpPost]
public ActionResult EditDetails(UserDetails userDetails)
{
    // note: the second overload is routeValues
    return RedirectToAction("Edit", userDetails.Id);
}

[HttpGet]
public ActionResult Edit(int id)
{
   var viewModel = service.GetUserViewModel(id);
   return View(viewModel); // reponse the ValidateLogin view
}

从其他帖子返回视图
